Surface plasmon resonance immunosensor is a relatively new immunoassay technique and has been receiving more and more attention in recent years. however, a major disadvantage of spr for bioanalytical applications is that low concentration or low molecular mass analytes could not be detected directly. therefore, it is a challenging task to develop strategies for improving the detection limit sensitivity of spr. in this paper, authors present a novel strategy for improving the sensitivity of spr immunosensing using streptavidinbiotinylated antibody complex. it is proven that the amplification strategy causes a dramatic improvement of the detection sensitivity. this amplification strategy is based on the construction of a molecular complex between streptavidin and biotin labeled protein. the complex can be formed in a crosslinking network of molecules so that the amplification of response signal will be realized due to the big molecular size of complex
